HAY-SLING.

SPECIFICATION forming part of Letters F'atent No. 348,950, datedSeptember 14, 1886.

Application filed March 20, 1886. Serial Nov 195,923.

To aZZ whom it may concern:

Be it known that I, ALLEN I. BOYER, of Jones, in the county of Cass anTlState of Michigan, have invented certain new and use ful Improvements inHay'Slings or Devices for Unloading Hay, of which the following is aspecification, reference being had to the accompanying drawings.

My improvements relate to that class of hayslings shown and described inUnited States Patent No. 280,159. I will therefore only de scribe somuch of a hay-sling as is necessary to show my improvements, whichrelate merely to a tripping device.

In the drawings, Figure 1 is a longitudinal central section on theline 1. 1 of Fig. 2; and

Fig. 2 is a longitudinal section on the line 2 2 of Fig. 1, taken atright angles with the section shown in Fig. 1.

Referring to the letters upon the drawings, A represents a casting, Bthe lifting-ropes, and U the trip. This casting is divided into threeparts, to two of which the lifting-ropes are applied, as illustrated,the third being a pivoted spring-latch, to which the trip-rope isapplied.

Referring to the details in this casting, D indicates the main part ofthe casting, which is hollow and provided at one side and one end, asillustrated, with a hollow cylinder or lifting-rope holder, E. Theobject of placing this lifting-rope holder in the position shown is thatthe trip-rope may be drawn under it, and thus cause the rope to operateupon the .pull the latch open.

latch at such an angle that it will more readily \Vhen the hay-sling isholding up a bundle of hay, the casting will occupy the inclinedposition shown in the drawings, and the trip-rope also be substantiallyas shown in position to act effectively for unlatching.

F indicates the spring latch, working with in the hollow casting D.

G indicates the sliding latch-bolt, provided with ahollow cylindricalliftingrope holder, as shown.

The operation ofthe device is as usual. The lifting-ropes being supposedto suspend a bunch of hay over where it is desired to deliverit, thetrip-rope is then pulled, which will cause the'latch to unlatch andrelease the sliding latclrbolt, which will result in dropping the bundleof hay.

Having thus described my improvements, what I claim to be new, anddesire to secure by Letters Patent of the United States, is-

The combination of the hollow casting I), provided with a ropeholder atone end, as shown, the spring-latch F, and the sliding latch-bolt G,with its cylindrical rope-holder, substantially as set forth. 7

In testimony whereof I have hereunto sub scribed my name.

ALLEN P. BOYER.
